2 A slight bend prior to a curve means that a 65 km/h curve advisory speed sign is not visible to drivers until 95 m.before the start of the curve. The 85th percentile speed of vehicles on this approach, prior to reaction and braking, has been measured by survey as 88 km/h. If it is assumed that it is desirable for vehicles to slow down to the posted 65 km/h-advisory speed before reaching the curve, what is the required distance to achieve this? Is the available sight distance adequate for this?

2 A slight bend prior to a curve means that a 65 km/h curve advisory speed sign is not visible to
drivers until 95 m before the start of the curve. The 85th percentile speed of vehicles on this
approach, prior to reaction and braking, has been measured by survey as 88 km/h. If it is
assumed that it is desirable for vehicles to slow down to the posted 65 km/h-advisory speed
before reaching the curve, what is the required distance to achieve this? Is the available sight
distance adequate for this?
